Silicon Metal is a very important industrial product can be used in steel-making, cast iron, aluminum (aviation, aircraft & automobile parts production), and silicon optoelectronic device and many other industries. It's known as the "salt" of modern industries. Metal silicon is made from quartz and coke in electric heating furnace smelting products. The main ingredient of silicon content is about 98%. The rest of impurities is iron, aluminum and calcium etc.Silicon Metal lump was produced in electric heating furnace by quartz and coke. Quartz will be redox and became molten silicon liquid. After cooling, it will be solid as we see. The primal silicon metal lump is very large. Then it will be madeinto smaller lumps which we call standard size. Silicon Metal Lumps will be 10-100mm.Typical models includes: Silicon Metal 2202; Silicon Metal 3303; Silicon Metal 441; Silicon Metal 553, Silicon Metal Off Grade.Application of Silicon Metal★ Aluminum alloy ingot production, as additive of silicon content.★ Dioxidizer in steelmaking as replacement of ferrosilicon.★ As raw materials to produce poly-crystalcon.
